SUMMARY:OpenCL-Enabled Parallel Raytracing for Astrophysical Application o
 n Multiple FPGAs with Optical Links
DESCRIPTION:Workshop\n\nOpenCL-Enabled Parallel Raytracing for Astrophysic
 al Application on Multiple FPGAs with Optical Links\n\nFujita, Kobayashi, 
 Yamaguchi, Boku, Yoshikawa...\n\nWe have optimized the Authentic Radiative
  Transfer (ART) method to solve space radiative transfer problems in early
  universe astrophysical simulation on Intel Arria 10 FPGAs as earlier work
 .  In this paper, we optimize it for the latest FPGA -- Intel Stratix 10 a
 nd evaluate its performance comparing with GPU implementation on multiple 
 nodes.  For the multi-FPGA computing and communication framework, we apply
  our original system named Communication Integrated Reconfigurable CompUti
 ng System (CIRCUS) to realize OpenCL base programming to utilize multiple 
 optical links on FPGA for parallel FPGA processing, and this is the first 
 implementation of real application over CIRCUS.\n\nThe FPGA implementation
  is 4.54 times, 8.41 times, and 10.64 times faster than that of GPU on 1 n
 ode, 2 nodes, and 4 nodes, respectively, for multi-GPU cases with InfiniBa
 nd HDR100 network.  It also achieves 94.2% parallel efficiency running on 
 4 FPGAs.  We believe this efficiency is brought from CIRCUS's low-latency 
 and high-efficiency pipelined communication which provides easy programmin
 g on multi-FPGA by OpenCL for high performance computing applications.\n\n
